Is a seller required to disclose all problems with a home?

Sellers are required to disclose known material defects that would affect a buyer's decision to purchase or the price they'd pay. They're generally not required to actively investigate and discover problems they don't know about. However, failing to disclose a known material defect is grounds for a lawsuit in virtually every state. The key word is 'known' — sellers can't disclose what they genuinely didn't know, but they can't hide what they did.

What is the most commonly undisclosed issue in real estate?

Water intrusion and past flooding is the most commonly concealed issue. Sellers may paint over water-stained walls, replace damaged drywall, or simply not mention past basement flooding. This is why looking for evidence of water damage during your inspection is critical, and why asking specifically about water intrusion on the disclosure form — and following up with inspectors — is so important.

What happens if a seller lies on the disclosure?

If a seller knowingly misrepresents or omits a material fact on a disclosure form, you have legal recourse — including rescinding the purchase, demanding repair costs, or suing for damages. The practical challenge is proving the seller knew about the issue. Document everything during due diligence: your inspection findings, any evidence of prior repair attempts, and any statements made by the seller or their agent.

What Is a Seller's Disclosure and Why Does It Matter?

May 31, 2026

What a Seller's Disclosure Is

A seller's disclosure (also called a seller's disclosure statement or property condition disclosure) is a form completed by the seller that documents the known condition of the property, including material defects, past repairs, legal issues, and environmental hazards. It's completed before the sale and given to buyers as part of the purchase contract package.

Disclosure requirements vary by state — some states have detailed mandatory disclosure forms; others leave it to the parties to negotiate what's required. In most states, disclosure is required by law, and failing to disclose a known material defect exposes the seller to significant legal liability.

What Sellers Typically Must Disclose

While the specifics vary by state, most seller's disclosures cover:

Structural issues: Foundation problems, roof condition and age, wall/ceiling defects
Water and moisture: Past flooding, basement water intrusion, drainage issues, history of leaks
Mechanical systems: HVAC condition and age, plumbing issues, electrical problems
Environmental hazards: Lead paint (required federally for pre-1978 homes), asbestos, mold, radon, underground storage tanks
Legal and title issues: Easements, encroachments, pending litigation, HOA violations, unpermitted additions
Pest history: Termite or wood-destroying organism history and any treatments
Neighborhood issues: In some states, nuisances, noise issues, or neighbor disputes must be disclosed

What Sellers Don't Have to Disclose

There are notable exemptions in most states:

Things they genuinely don't know: Sellers can't disclose what they're unaware of — but courts look skeptically at claimed ignorance of visible, obvious problems
Stigmatized property issues: In many states, sellers don't have to disclose that a crime or death occurred in the home (though some states do require this)
Issues discovered in inspections they didn't order: Sellers aren't usually required to proactively inspect and discover new problems — though once a problem is found during due diligence and disclosed, it becomes a known fact

How to Use Disclosures During Due Diligence

Read Every Line

Disclosure forms vary from 2 pages to 15+ pages. Read every question and every answer. Pay special attention to anything marked "unknown" — this can sometimes be a seller avoiding a direct yes/no answer about a problem they're aware of.

Cross-Reference With Your Inspection

Give your home inspector a copy of the seller's disclosure before the inspection. Ask them to specifically evaluate any areas where the seller disclosed past issues (or conspicuously didn't disclose anything about areas with visible repair evidence). An inspector who finds fresh paint covering water stains that weren't disclosed has uncovered something important.

Ask the Right Questions

Your buyer's agent can formally ask the seller's agent for additional information about anything in the disclosure that raises questions. Get answers in writing — verbal representations without written follow-up are harder to enforce.

Work With an Agent Who Knows Disclosure Requirements

An experienced buyer's agent knows the disclosure requirements in your state and can flag anything in the disclosure that deserves closer scrutiny. Find experienced buyer's agents in your market on The Realtor Rankings.
